Many years ago I found this story, I think in Stern, about men prisoners feeding cats in the Aichach prison:
Fortunately I have found my old copy and sent it to Jimmy’s Catladder blog.
I can’t find anything about it now. Possibly the ladders have gone. I think the big windows at the ends of blocks are the kitchens where the prisoners can make themselves food in their break times and presumably fed cats too. It’s mainly a women’s prison, but I think it was in the men’s section that the cats were.
